Solution

Moment of inertia is defined as the quantity expressed by the body resisting angular acceleration which is the sum of the product of the mass of every particle with its square of a distance from the axis of rotation.
The moment of inertia is a scalar quantity.
The moment of inertia can be written as: $I = m \times r^{2}$ where $I$ is the moment inertia, $m$ is the mass, $r$ is the distance from the axis of the rotation.
It is the opposition exhibited by a body that is under rotation due to the torque.
The unit of the moment of inertia is kilogram-meter-square.
The moment of inertia of a rigid body does not change with the speed of rotation.
